IAEA SAFETY STANDARDS Construction for Nuclear Installations

commissioning are fully compliant with all of the above requirements, a high level of safety
can only be achieved when the construction is carried out with high quality and care, since
commissioning cannot test all aspects of the design. Therefore all construction activities have
a potential impact on safety, although no nuclear material may be present during the
construction.
OBJECTIVE
1.4 The objective of this Safety Guide is to provide recommendations and guidance
based on international good practices in construction of nuclear installations, as currently
followed in Member States, which will enable construction to proceed with high quality,
consistent with applicable codes, standards, and design requirements as part of the
demonstration that the product can be commissioned and is capable of operating safely and
reliably over its lifetime.
SCOPE
1.5 This Safety Guide is applicable to the construction stage of a new nuclear installation
and the modification of an existing nuclear installation 1 , including the process of
manufacturing and assembling the components, carrying out of civil and architectural work,
installation and maintenance of components and equipment, and performing the associated
tests. Neither the design nor commissioning stage is included in this Safety Guide, although
1 NS-G-2.3 “Modification to Nuclear Power Plants” [9] provides guidance on controlling activities relating to
modifications at nuclear power plants and it deals with the intended modification of items, operational limits and
conditions, procedures and software, and the management systems and tools for the operation of a nuclear power
plant.
